Abstract
Description
Technical Field
[0001] This invention relates to the field of needle roller screening technology, specifically to an automated needle roller identification device and sorting machine. Background Technology
[0002] Needle rollers refer to the rotating parts on a needle roller bearing. They are mainly used in various types of bearings and are roller bearings with cylindrical rollers that are thin and long like needles. These bearings have a high load-bearing capacity and a compact radial structure. However, they usually need to be sorted after production and before assembly to fit different sizes of bearings for installation.
[0003] Existing screening and sorting methods typically involve setting several circular holes on a turntable, with needle rollers falling into one of these holes. Simultaneously, the base also has several screening holes of various sizes. The turntable rotates until the circular holes align with the screening holes, at which point it stops. The needle rollers then fall into the screening holes and are collected in a collection box. This results in the turntable needing to stop-start-stop during screening, leading to low overall screening efficiency. Summary of the Invention

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0034] Please see Figure 1-8 An automated needle roller identification device and sorting machine includes a base 1 and a base platform 2. The base platform 2 is fixedly installed on the base 1. It also includes a turntable 51, which is rotatably installed on the base platform 2. The turntable 51 is provided with a plurality of discs 52, and the discs 52 are provided with arc-shaped grooves 52.1.
[0035] The material feeding mechanism is located above the turntable 51, and includes a flexible tube 37 and a rigid tube 38, with the rigid tube 38 located below the flexible tube 37.
[0036] The material feeding chute 2.2 is set on the base 2 and is used to identify and screen needle rollers of different diameters;
[0037] When the turntable 51 rotates, the disc 52 on it is passively rotated to the same radial direction as the turntable 51 when it is close to the bottom of the rigid tube 38, so as to facilitate the receiving of the needle roller body 4 inside the rigid tube 38. After the disc 52 receives the needle roller body 4, it is passively rotated and reset again to facilitate subsequent screening.
[0038] A baffle 312 is fixedly installed on the connecting column 31, and a rigid tube 38 is fixedly installed on the baffle 312 to maintain stability. A flexible tube 37 is installed above the rigid tube 38 and connected to the bundle tube 35 to facilitate vibration.
[0039] Several collection boxes 6 are also inserted inside the base 2. The collection boxes 6 are provided with through holes and are connected to the discharge chute 2.2, so as to facilitate the collection of the needle rollers screened out by the discharge chute 2.2.
[0040] The base 2 is equipped with a drive motor, which drives the turntable 51 to rotate.
[0041] In another embodiment of the present invention: the material feeding mechanism includes a connecting column 31 fixedly installed on the base 2, a vibrator 32 fixedly installed on the connecting column 31, and a connecting frame 36 fixedly installed at the output end of the vibrator 32;
[0042] A connecting rod 33 is fixedly installed at the top of the connecting column 31, a storage frame 34 is fixedly installed on the connecting rod 33, and a stirring mechanism is provided at the top of the connecting rod 33.
[0043] A bundle tube 35 is provided at the bottom of the storage frame 34. The bundle tube 35 is set inside the connecting frame 36 to receive the vibration of the vibrator 32.
[0044] A gap for vibration is provided between the bundle tube 35 and the storage frame 34, and the top end of the hose 37 is fixedly installed inside the bundle tube 35. The inner wall of the bundle tube 35 is shaped like a frustum, with a larger upper dimension and a smaller lower dimension. The lower dimension is matched with the size of the hose 37, so that after the needle roller enters the bundle tube 35, it can slide down along the inner wall of the bundle tube 35 into the hose 37.
[0045] Furthermore, the hose 37 is provided with three or more channels, so that the needle rollers can fall from the storage frame 34 into the bundle tube 35 and then enter the hose 37 through more channels, thereby enabling more needle rollers to be delivered at the same time.
[0046] In another embodiment of the present invention: the stirring mechanism includes a top plate 71 fixedly installed at the top of the connecting rod 33, a servo motor fixedly installed on the top plate 71, and a stirring rod 73 rotatably installed on the top plate 71. Both the stirring rod 73 and the servo motor are provided with pulleys, and a belt 72 is provided between the two pulleys.
[0047] The belt 72 is driven by a servo motor, which in turn drives the stirring rod 73 to rotate. The stirring rod 73 is located at the center of the storage frame 34, and a notch can be provided on the stirring rod 73. When the stirring rod 73 rotates, it can drive the needle rollers gathered in the storage frame 34 to move, thereby preventing the needle rollers from getting blocked on the bottom wall of the storage frame 34. The notch makes it easy to drive the needle rollers to move, and the needle rollers can fall more easily from the bottom of the storage frame 34 from the notch position.
[0048] The vibrator 32 has a positioning frame on its surface, and the positioning frame is located at the bottom of the connecting frame 36. The bundle tube 35 passes through the positioning frame but does not contact the positioning frame, thereby avoiding the influence of the positioning frame.
[0049] In another embodiment of the present invention: a rotating block 39 is rotatably mounted on the surface of the rigid tube 38, a long strip 310 is fixedly mounted on the rotating block 39, and a baffle 311 is fixedly mounted on the long strip 310;
[0050] The bottom end of the rigid tube 38 has a notch, and the notch faces the conveying direction of the turntable 51;
[0051] A reset spring is provided between the rotating block 39 and the rigid tube 38;
[0052] When the needle rollers fall into the arc-shaped groove 52.1 of the disc 52, and the arc-shaped groove 52.1 is located below the rigid tube 38, it is arranged radially along the turntable 51, thereby collecting a number of needle rollers. (Refer to...) Figure 5The conveying direction of the turntable 51 is counterclockwise. When the turntable 51 rotates, the bottom end of the needle rollers abuts against the turntable 51 until a certain disc 52 rotates to below the rigid tube 38. At this time, when the arc groove 52.1 on it rotates to be set along the radial direction of the turntable 51, its length direction is directly facing several needle rollers, so that several needle rollers can be collected at the same time. When the needle rollers reach the position of the arc groove 52.1 on the disc 52, they will fall naturally into the arc groove 52.1 by gravity. At this time, as the turntable 51 rotates, it will drive several needle rollers to move in the counterclockwise direction. At this time, the baffle 311 will open to the left through the rotating block 39, so that the top end of the needle rollers can be moved out from the open position of the baffle 311.
[0053] The return spring can be set between the long strip 310 and the rigid tube 38. The return spring can make the baffle 311 always cover the notch. At this time, a channel is still formed between the baffle 311 and the rigid tube 38 to facilitate the vertical sliding of the needle until the bottom of the needle contacts the turntable 51. At this time, the top of the needle is located in the middle of the baffle 311. However, when the bottom of the needle contacts the turntable 51 and is affected by the friction of the turntable 51, the return spring can pull the baffle 311 to lock the needle and overcome the friction between it and the turntable 51 until the needle falls into the arc groove 52.1, which can make the disc 52 drive the needle to move.
[0054] In another embodiment of the present invention: a friction element 54 is rotatably mounted inside the turntable 51, and the cross section of the friction element 54 is T-shaped. The friction element 54 is provided with an upper friction wheel and a lower friction wheel, and the size of the upper friction wheel is larger than that of the lower friction wheel.
[0055] Friction strips 55 are fixedly installed on the base 2;
[0056] The lower friction wheel engages with the friction strip 55, and the upper friction wheel engages with the disc 52;
[0057] There are two friction strips 55, and the two friction strips 55 are located at the two ends of the friction element 54, respectively. Figure 5 When the turntable 51 performs counterclockwise conveying and screening, the lower friction wheel will contact the friction strip 55 near the center of the turntable 51. At this time, the friction strip 55 will drive the friction element 54 to rotate counterclockwise, and at the same time, the upper friction wheel of the friction element 54 will drive the disc 52 to rotate clockwise until the arc groove 52.1 on the disc 52 is set along the radial direction of the turntable 51. When the arc groove 52.1 takes away the needle rollers, the friction element 54 will separate from the inner friction strip 55. At the same time, the friction element 54 will contact the friction strip 55 away from the center of the turntable 51. At this time, the friction element 54 will rotate in the opposite direction and drive the disc 52 to rotate in the opposite direction to reset. At this time, the arc groove 52.1 will be aligned with the discharge chute 2.2.
[0058] In another embodiment of the present invention: a limiting plate 53 is fixedly installed on both the upper and lower surfaces of the disk 52, and a groove 2.1 is provided on the base 2;
[0059] The limiting plate 53, which is set in the vertical direction, can easily install the disc 52 in the turntable 51, and the groove 2.1 on the base 2 facilitates the movement of the limiting plate 53 below the disc 52. The end of the limiting plate 53 away from the disc 52 is provided with a chamfer, so that the disc 52 will not be obstructed when it rotates and the limiting plate 53 comes into contact with the needle roller.
[0060] In another embodiment of the present invention: a limiting block 56 is fixedly installed on the turntable 51;
[0061] The disc 52 is frictionally connected to the friction element 54. As the friction element 54 rotates, it will drive the disc 52 to rotate clockwise or counterclockwise until the limiting plate 53 on the disc 52 contacts the limiting block 56 and stops moving.
[0062] In another embodiment of the present invention: the top end of the material discharge chute 2.2 is provided with a chamfer;
[0063] The upper part of the feed chute 2.2 is chamfered, which makes it easier for the needle rollers to fall into the feed chute 2.2 through the chamfer;
[0064] The material discharge troughs 2.2 are arranged in several directions along the circumference of the base 2, and the width of the material discharge troughs 2.2 increases sequentially along the conveying direction of the turntable 51. This allows the larger-sized needle rollers to pass directly over the material discharge troughs 2.2 when the needle rollers approach them in sequence, while the smaller-sized needle rollers fall down along the material discharge troughs 2.2 at the beginning for screening.
[0065] In another embodiment of the present invention: a protrusion 2.3 is fixedly installed on the chamfer of the material feeding chute 2.2;
[0066] Among them, reference Figure 8 The conveying direction of the turntable 51 is from left to right. At this time, the angle of the protrusion 2.3 along the conveying direction of the turntable 51 is from small to large. It is first a gentle slope with a small angle, and then a steep slope with a large angle on the right. Therefore, when the disc 52 drives the needle roller to move to a position close to the drop chute 2.2 through the arc groove 52.1, the rightmost needle roller will first contact the protrusion 2.3. Its bottom end will be lifted by the protrusion 2.3, thereby raising itself. Then, it will quickly descend when it is close to the steep slope on the right, so that the needle roller raised on the right and the needle roller on the left can quickly separate in a short time, so that the needle roller on the right is not squeezed and can fall quickly in the appropriate drop chute 2.2.
[0067] When the disc 52 drives several needle rollers to move through the arc-shaped groove 52.1, the needle rollers will sink within the arc-shaped groove 52.1 until their bottom ends are in contact with the surface of the base 2. Therefore, during the conveying process, the needle rollers within the arc-shaped groove 52.1 will move backward due to the friction between their bottom ends and the base 2, and will gather at the tail end of the arc-shaped groove 52.1. At this time, the needle rollers will gather together, and if the needle rollers in the middle and at the very end have not yet been screened and fallen off, they will easily be squeezed together and subjected to friction, thus causing... Since the material cannot fall quickly and naturally within the suitable discharge chute 2.2, a protrusion 2.3 is provided above the discharge chute 2.2. The surface of the protrusion 2.3 is flush with the arc-shaped inner wall of the discharge chute 2.2, so that the protrusion 2.3 will not affect the screening of the discharge chute 2.2. At the same time, within the discharge chute 2.2, after the needle rollers in the conveying direction are lifted by the protrusion 2.3, they will fall quickly through the steep slope and separate from the adjacent needle rollers in a short time, thereby reducing the squeezing force on the adjacent needle rollers and making it easier for them to pass through the discharge chute 2.2 and be screened.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
